In a spark gap device a number of arc-resistant insulating elements are stacked in spaced relationship to form spaces between adjacent insulating elements with each element having a through-hole. At least two metallic electrodes are sandwiched between the respective surfaces of adjacent insulating elements in spaced relation to form a spark-over gap therebetween. Each electrode includes a recessed portion and the recessed portions of aligned electrodes on respective opposite sides of an insulating element extend through each of the through-holes in contacting relationship. The insulating elements each include at least one elevation which projects snugly into the recessed portion of an associated electrode. |
